Open system probes of renormalization group flow
Andrew Keefe, Brenden Bowen, Saptarshi Biswas +3
Open system probes can provide an efficient means to characterize quantum many-body systems by employing them as engineered environments. The key idea is to map long-range spatial…
High-fidelity iSWAP gate with Double Transmon Coupler
Tarush Tiwari, Sudhir K. Sahu, Guilhem Ribeill +6
Entangling operations are at the heart of all approaches to quantum information processing. Parametric gates, in particular, offer a versatile solution to strongly couple off-reson…
Practical Limits to Single-Mode Vacuum Squeezing with a SNAIL Parametric Amplifier
Theodore Shaw, Debsuvra Mukhopadhyay, Zhuoqun Hao +4
We characterize single-mode vacuum squeezing generated by a SNAIL Parametric Amplifier (SPA) operated under conditions representative of practical sensing and qubit-readout experim…
Long-range waveguide-quantum electrodynamics with left-handed transmission lines
P. Goswami, J. Liu, C. A. González-Gutiérrez +1
While engineering long-range light-matter interactions is the principal aim in waveguide-QED, ironically most of the building blocks rest on local short-range couplings, such as ne…
Coherent and compact van der Waals transmon qubits
Jesse Balgley, Jinho Park, Xuanjing Chu +9
State-of-the-art superconducting qubits rely on a limited set of thin-film materials. Expanding their materials palette can improve performance, extend operating regimes, and intro…
Unified trajectory criterion for quantum and classical non-Markovianity
Le Hu, Archana Kamal
We propose a simple criterion for non-Markovianity: a quantum master equation is non-Markovian if and only if its \textit{trajectory set} contains a \textit{self-intersecting traje…
Tutorial: Understanding quantum Zeno and anti-Zeno regimes
Sacha Greenfield, Archana Kamal, Justin Dressel +1
The quantum Zeno effect is a striking feature of quantum mechanics with foundational implications and practical applications in quantum control, error suppression, and error correc…
Quantifying spectral signatures of non-Markovianity beyond the Born-Redfield master equation
A. Keefe, N. Agarwal, A. Kamal
Memory or time-non-local effects in open quantum dynamics pose theoretical as well as practical challenges in the understanding and control of noisy quantum systems. While there ha…
